fitting the front drive shaft in this age bracket is tricky.
However, one answer will help tremendously.
Taking a look at the transfer case tail housing-(where the rear drive shaft comes out)
Look for a sensor with a wire harness. Or, if you could take a picture of the left (driver) side of the tail housing it would help.
Also, if you could get a picture of the front output where the front shaft meets the transfer case.
What we are looking for is to see if your transfer case has the speed sensor. Some do, and some do not in this time frame.
If you do have the speed sensor, you need a front prop shaft for early 97.
If you do not have the sensor, the drive shaft may need to be measured.
This is pretty easy to do.
PIctures would help. Post them to a free picture site like

then just post the links back in here.
